STARCHPRINTER.

SPECIFICATION forming part of Letters Patent No. '7 07,589, dated August 26, 1902.

Application filed January 2., 1902. Serial No. 88,104. (No model.)

To @ZZ whom, it may concern:

Be it known that I, DANIEL M. HOLMES, a citizen of the United States, residing in Arlington, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Starch-Printers,of which the following is a specification.

My invention relates especially to devices employed for printing molds in starch or kin# :o dred material, and has for its object the provision of a printer whereby perfect, smooth, and uniform molds may be formed.

To attain the desired end,my invention consists, essentially, in the combination, with a vertically-movable platen, of means for imparting a horizontal eccentric movement to the same; and my invention also involves certain other novel and useful combinations or arrangements of parts and peculiarities of conzo struction and operation, all of which will be hereinafter first fully described and then pointed out in the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is an end elevation, and

Fig.2 a side elevation, of my improved starchprinter.

Similar numerals of reference Wherever they occur indicate corresponding parts in both gures.

3o l is the main frame of the printer, and 2 is the bed, having a horizontal slot 3 therethrough.

4 represents standards mounted upon theV main frame at each side of the center. 5 is a driving-shaftprovided with apulley 6. 7 is an elliptical gear upon the shaft 5, which engages a corresponding gear 8 upon a shaft 9. This shaft 9 bears at each extremity a crank 10, engaging with a rod 11, which passes 4o to a platen 12 for carrying printing-forms 13.

Upon the shaft 9 is fixed a gear 14, which engages with a gear 20 on a Shaft 15, having at each end a ruiter-gear 16, meshing with a corresponding gear 17 upon the lower extremity of vertical shafts 18, mounted in bearings 21 and 22, projecting from the main frame and journaled at their upper ends in the Standards 4. The portions 19 of the vertical shafts 18 are made slightly eccentric and constitute the guides upon which the platen moves, the 5o object of this construction being'explained below.

Upon the driving-shaft 5 is a gear 23, meshing with an intermediate gear 24, mounted upon a stud fixed in the main frame, said gear 25Jc meshing with a gear 25 on a shaft 26. At each end of the shaft 26 is a crank 27, engaging with a connecting-rod 28, pivoted to a rock-arm 29, held at 30 at its lower end to the main frame and engaging with a rod 31, pass- 6o ing to a rod 33, which extends through a horizontal bar 32 at each side of the bed 2 and through the slot 3 therein, the rods 33 and bars 32 constituting a slidable frame having at each side a spring-actuated finger 34, arranged to contact with a starch-tray 35.

Heretofore in Starch-printers it has been found necessary to jar the printing-form or employ cams for obtaining a double impression inorder to acquire smooth uniform molds. 7o By my invention both of these requirements are dispensed with, as when the platen moves vertically it is also caused to have a horizontal slightly-eccentric movement through the medium of its eccentric rotary guides, and the result of Such movement is to cause the printing-forms to firmly pack and smooth the starch While forming the molds.

In supplying the Starch-trays to the printer they are placed upon the left-hand end of the 8o bed. The movement of the mechanism brings the bars 32 to the left, the spring-actuated lingerspassing beneath the tray until the bars move sufficiently to cause the fingers to rise and engage the side of the tray, the reverse movementof the bars 32 carrying such tray to the position shown in the drawings, this movement pushing the tray in which the starch has been printed out of the way, thus automatically supplying andfremoving the 9o trays to and from beneath the printing-form.

Having now fully describedmy invention, what l claim as new therein, and desire to secure by Letters Patent, is.-

1. In a starcl1printer,the combination With 95 a vertically-movable platen, of means for imparting a horizontal, eccentric movement to therewith, substantially as shown and deo the same. K y scribed.

2. In a stareh-printer,the combination with Signed by me at New York this 15th day of a vertically-movable platen, of rotatable, ee- November, 1901. centric guides therefor.

3. In a stareh-prnte1,the combination With l the bed and a starch-tray, of horizontally-mov Witnesses able bars bearing spring-actuated fingers ar- A. M. PIERCE, ranged to pass beneath a tray and engage C. L. DAVIS.
